On July 2, Roundhill Memory ETF declined 5.53% in regular trading, trading at $62.02/share, with turnover of $1.956 billion.

On the news front, Meta announced plans to enter the cloud infrastructure services market by selling its excess AI computing resources externally. This move triggered widespread fears of computing power oversupply, sending the Philadelphia Semiconductor Index down over 6%. Storage chip leaders Micron Technology and SanDisk each plunged more than 10%, while in South Korea, the stock market triggered a circuit breaker mechanism, with Samsung Electronics falling over 7% and SK Hynix dropping more than 8%.

Compounding the pressure, Samsung, SK Hynix, and Micron are facing a class-action lawsuit filed in a U.S. federal court in California alleging conspiracy to manipulate DRAM prices, with plaintiffs seeking treble damages. All three companies have prior antitrust convictions, intensifying market concerns. The ETF's top three holdings — Samsung Electronics, Micron Technology, and SK Hynix — account for over 74% of total weight, making the fund highly vulnerable to systematic sector selloffs.
